Confucianism: I asked someone and said that our place is a place for literati and it is not suitable for joint weddings. Do it if you have to, and don't make too much noise. The Tian Yue Garden near my home is nice, but there is no venue for the wedding in the hall. You'd better go and have a look.
Don't think about Guo Lin. They say that booking in advance 1-2 years is almost the same. Fengtai police station has a family named Datang pear, which is not bad either. There are many restaurants in Qilizhuang. Go and have a look around, hehe.
